Jim Harbaugh, the younger brother of Ravens Head Coach John, had a minor procedure for an irregular heartbeat on Thursday.
The 49ers head coach missed Thursday's practice to undergo the surgery at Stanford Hospital, but he was back at the team's facility on Friday. John said that he's talked with his brother and that he is doing well.
"He's feeling good," John said on Friday. "He's back at work today, from what I understand."
John also indicated that Jim has dealt with an irregular heartbeat previously and that the procedure should correct the issue.
"I guess it's a little bit more advanced now with his heart rate and things like that, so it should correct that," John said.
Jim's 49ers (6-2-1) are in first place in the NFC West and are preparing for this week's matchup against the Chicago Bears (7-2) on Monday Night Football.
